This grade is, however, not necessarily permanent, for what was baselevel for a small stream in an early stage of its development, is not necessarily baselevel for the larger stream which succeeds it at a later time.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "baselevel" in a variety of sentences. We hope that you will now be able to make sentences using this word.
